How can the normalization of database tables impact the handling of null values in PHP applications?

Normalizing database tables can impact the handling of null values in PHP applications by enforcing data integrity rules that prevent the insertion of null values into columns that should not allow them. This can lead to more consistent and reliable data storage and retrieval processes in the application. 

// Example PHP code snippet to handle null values when inserting data into a normalized database table
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

$stmt = $pdo->prepare("INSERT INTO users (name, email) VALUES (:name, :email)");

$name = isset($_POST['name']) ? $_POST['name'] : null;
$email = isset($_POST['email']) ? $_POST['email'] : null;

$stmt->bindParam(':name', $name, PDO::PARAM_STR);
$stmt->bindParam(':email', $email, PDO::PARAM_STR);

$stmt->execute();
